A taxis (from Ancient Greek τάξις (táxis) 'arrangement, order'; [1] pl.: taxes / ˈ t æ k s iː z /) [2] [3] [4] is the movement of an organism in response to a stimulus such as light or the presence of food. Taxes are innate behavioural responses.
"Fixed action pattern" is an ethological term describing an instinctive behavioral sequence that is highly stereotyped and species-characteristic. [1] Fixed action patterns are said to be produced by the innate releasing mechanism, a "hard-wired" neural network, in response to a sign/key stimulus or releaser.
Instinct is the inherent inclination of a living organism towards a particular complex behaviour, containing innate (inborn) elements.The simplest example of an instinctive behaviour is a fixed action pattern (FAP), in which a very short to medium length sequence of actions, without variation, are carried out in response to a corresponding clearly defined stimulus.
The book models the animal world in a minimalistic and constructive way, from simple reactive behaviours (like phototaxis) through the simplest vehicles, to the formation of concepts, spatial behaviour, and generation of ideas. For the simplest vehicles, the motion of the vehicle is directly controlled by some sensors (for example photo cells).
Phototaxis can be advantageous for phototrophic bacteria as they can orient themselves most efficiently to receive light for photosynthesis.Phototaxis is called positive if the movement is in the direction of increasing light intensity and negative if the direction is opposite.
The road to autonomous driving is not for the faint of heart. Look behind to view the wreck of Uber’s self-driving car. In the ditch to the left is General Motors’ Cruise robo-taxi.
Animals can also use rheotaxis in conjunction with other methods to orient themselves in the water. For example, sea lamprey will use the flow of the current to identify upstream chemical stimuli, and position themselves towards the direction of the signal. [7] Rheotaxis is also a phenomenon seen in small scale artificial systems.
When Piaget formed his developmental theory in the 1950s, he claimed that object permanence is learned, not innate. The children's game peek-a-boo is a classic example of this phenomenon, and one which obscures the true grasp infants have on permanence. To disprove this notion, an experimenter designs an impossible occlusion event.
